  • Overview

Overview

Switching to a Three SIM only deal saves you money and if you’re moving from Pay Monthly it offers a shorter contract length, with 12 or 1 month plans available. You also get several benefits you won’t get on other networks including Wuntu rewards, Go Binge and unlimited data plans.

Why choose Three?

  • Reliability

Three is a major UK network, so you can be confident that it’s reliable. But that’s even more true for Three than others, as it’s regularly rated the most reliable UK network by independent companies.

  • Excellent value

It’s also cheap for a big-name brand, and that’s especially true if you opt for a SIM-only contract, as these are a lot less expensive than getting a smartphone included.

  • Unlimited data

If you’re fan of data Three is also well-worth considering as it offers tariffs with unlimited data, so you’ll never run out. Its rapidly expanding 4G network carries much of the nation’s mobile data – so it’s adept at handling it.

  • Choice

As well as unlimited data, there’s also a range of smaller allowances at lower prices, making it easy to find the perfect fit.

Added extras on SIM plans

  • Wuntu rewards

Once you join Three you’ll get free rewards and discounts every week. They include free pizza at Dominos, free coffee at Costa, free movie rentals and much more.

  • Go Binge

Go Binge enables you to use Netflix, Snapchat, Apple Music, Soundcloud, Deezer and TV Player without using any of your data allowance. It comes with all plans that have at least 12GB data.

  • Go Roam

Three lets Advanced Plan customers (which all currently available SIM Only plans are) roam for free in 71 destinations, many of which are outside Europe, such as the US and Australia. 

  • 4G Super-Voice

Another extra included is 4G Super-Voice (VoLTE), which lets you call over 4G, and helps plug signal blackspots for superior coverage.

  • WiFi Calling

WiFi calling is also supported on Three so you can stay in touch in bad signal areas. It’s supported app-free on many recent iPhone and Android phones, while those with older phones will just need to download the Three InTouch app to enjoy WiFi calling.

Is roaming included?

All plans on Three come with free roaming in 49 European countries. While Advanced Plans include free worldwide roaming in 71 countries including USA, Australia, New Zealand and many more.

Is tethering allowed?

Yes, all currently available SIM Only plans come with tethering included at no extra cost, and you can use as much of your data as you want, even if you have unlimited data.

How can I keep my number when switching?

All you need to do is sign up to Three, then request your PAC code from the network you’re leaving, and fill in Three’s transfer form. Transfers will be made the next working day if requested before 5pm Monday-Friday.

Which size SIM will I get?

You don’t need to worry about SIM size as Three will send you a Trio SIM, which comes with all SIM types. All you need to do is pop out the size you require, be it Standard, Micro or Nano.

Will there be a credit check?

Yes, Three will undertake a credit check, however it’s nowhere near as strict as when purchasing a contract phone. Therefore, it can be good for those who have previously been refused a phone contract and those with poor credit.
